Hello: I am trying to configure solaris on my system to send email. The functionality that I want to achieve is to have a java application running on the system use sendmail to send email to outside world. this java appl will run as a solaris user, but is web based application that will be used to send email after a form is filled out. Email has to be sent to multiple addresses and multiple domains Configuration and setup: 1. Solaris host is behind a NAT (domain1.com) 2. host resolves to http://domain2.com 3. host also resolves to host.domain1.com (automatic since behind domain1.com firewall) 4. internally, host also responds to private internal IP Right now, sending email says: Relaying denied, IP name lookup failed [Public IP of NAT/Firewall here] What settings should I have in my /etc/hosts /etc/mail/local-host-names for this to work ? I apologize if this sounds complicated than it should be, but that is precisely why I need the help !

I must also add that both host.domain1.com and domain2.com respond to a commmon public IP. Therefore, we have Public IP of NAT/Firewall: xx.xx.xx.200 Public IP for host.domain1.com and http://domain2.com : xx.xx.xx.201 Public IP for www.domain1.com xx.xx.xx.201 Hope that helps

Your error message is saying that the public IP address of your router does not resolve to a hostname and as such is not trusted as a mail host. Find a DNS provider to assign a hostname to that IP address.

I can rephrase this question. I am trying to send email from a local solaris machine that has an external public address (resolves to a dns) and also behind a Firewall/NAT. When I send email, using sendmail -- the mail carries the NATTED IP Address with it -- to resolve which, the traffic hits my Firewall/IP and my firewall does not have a public A/PTR record. -- therefore I get a IP name lookup failed. How can I get the email to go out with the public address of my solaris server so that the reverse name lookup does not fail.

forget sendmail man........it SU*KS get surgemail...........its fantastic and so easy its not even funny google surgemail......... you life will be so much easier man
